CARBURETO R.

SPECIFICATION forming part of Letters Patent No. 353,311, dated November30, 1886. Application filed December B, 1885. Serial No. 185,085. (N omodel.)

To aZZ whom it may concern:

Beit known that I, PETER KELLER, a citizen of the United States, and aresident of New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Carburetors, ofwhich the following is a specification.

My invention relates to carburetors for sup` plying illuminating-gaswith the vapor of hydrocarbon liquid, as will be fully set forth in thefollowing description thereof.

My invention consists of a float-valve composed of a disk with keels onthe under side thereof and a projecting lobe on the upper portionthereof, which is connected with a spring terminating in a straight rod,which extends upward through an opening madein the central portion ofthe diaphragm. Said rod is supported in a vertical position by means ofguides. The lower edge of the opening surrounding the valve-rod isarranged so as to form a seat into which a corresponding-shaped valvefixed to the aforesaid valve-rod fits.

In the accompanying drawings, Figure 1 represents a vertical centralsection of my carburetor. Fig. 2 represents a top and inverted plan.Fig. 3 represents a cross-section of the carburetor. Fig. 4 represents afilling-can.

Similar letters refer to similar parts throughout the drawings, in whicha represents the storage-chamber for the hydrocarbon liquid, and thelower compartment I term the evaporating-chamber7 b. The top of thestoragechamber is provided with a Vent and llingtube, c c', each ofwhich isprovided with stopcocks ci d', and also with screw-caps e e',for closing the end of said tubes. The storage and evaporating chambersare formed by a diaphragm, f, in the center of which is an opening, g,through which passes a valve or guide rod, lz, carrying a valve, t',fixed thereto and of suitable form adapted to correspond with the seatk, made around the said opening g, through which the valve or guide rodpasses. This guide-rod terminates in the shape of a spring, Z, below theaforesaid valve i, and the lower end of the spring is secured to afioatvalve, m, consisting of a disk, m', having an upwardly-projectinglobe, m2, adapted to close the lower end of the spout n, projectingdownwardly from the diaphragm. The bottom of the float -valve isprovided with keels ma,

adapted to prevent the same from being easily removed from a horizontalposition.

Secured to the bottom of the evaporatingchamber, and arranged around thefloat-disk, are four vertical pins, o, serving as guides for the float,and thus preventing it from swinging beyond the vertical line of thespout against the end of whichiit is designed to operate. That portionof the guide or valve rod located within the storage-chamber is guidedin a vertical position by means of the guideyoke p, secured to the upperportion of the diaphragm, and the guidesleeve p', secured to the lowerportion of the top of the storagechamber. The vessel forming the storageand evaporating chambers is hermetically sealed, and placed within andentirely covered by another vessel, r, provided with an annular hollowprojection, s, on the top thereof and inclosing both the kVent andfilling tubes of the storagechamber. This hollow projection s isprovided with a cover, s', adapted to be locked or otherwise fastenedthereto. There is in the base of the hollow projection an opening, t,through which water is supplied until it shall have reached above thevent and iilling tubes o c.

Arranged diametrically opposite each other are two vertical pipes, o o2,passing from the main gas-,conduit o, and extending therefrom to theevaporating-chamber. One of these vertical pipes extends at a suitabledistance below the diaphragm of the evaporating-chamber, the otherstopping hush with the base thereof.

Mode of operation: The gas passes from the main conduit 'u to thegas-supply pipe o', thence to the evaporating-'chamber b, where itbecomes carbureted while passing through the hydrocarbon vapor t-o theoutlet-pipe o2, from which it passes to the various branches forilluminatin g purposes. The constant evaporation of the hydrocarbonliquid will cause its level to descend, carrying with it the float-valvem, which in turn causes the valve i to leave the seat k, leading intothe storage-chamber @,when the hydrocarbon liquid begins to descendthereupon and continues until the liquid shall have reached itspredetermined height within the evaporating-chamber b, when the valveswill have closed all communication with the storage chamber Thisoperation continues IOO until the sto'rngeebaniber shall have beenexhausted, when the cover is removed and the filling-tubes of thecarburetor are Connected with the tubes of the hydrocarbon-liquid can, 5thus resupplying the storage-cimmber.

Having thus described my inventioinwhat I claim as new7 and desire t-osecure by Letters Patent, is-

In combination with a Carburetor7 the iioatio valve Composed of the diskwith keels ou the lower surface thereof, and the upwardly-projectinglobe on the upper surface of the same,

and Connected with a spring terminating in a straight rod operating inthe guides, and the valve fixed to said rod above the spring afore- :5said, substantially its shown and described.

Signed zbt New York, in the county of New York and State of New York,this 14th day of April, A. D. 1885.

PETER KELLER.
